Capri

A 45ft x 14ft dual steer with a semi-deep-vee chine hull configuration. 

The brochure describes it as an architect designed dream cottage.

This was a very different offshore design.  The previous models had been designed for inland leisure use.

I am unsure how many were built, but it was a relatively small number, possibly only a handful.  Each one appears to have visual build differences.  

A single steer version was fitted at Richardson's around 1979 as 12 berth Regal Gem for their (then) Thames fleet, Bushnell's of Maidenhead.  She ended her hire life as Miss Thelma at Thames Ditton in 2002.
